Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What happens when the slope of a node is +2?
- Left Rotation
- Right Rotation
- No Rotation
💡 Hint: Think about how we correct balance favoring the left subtree.
Question 2
True or False: Heights must be computed recursively for every tree operation.
- True
- False
💡 Hint: Remember why it's inefficient to compute heights all the time.

Challenge Problems
Push your limits with challenges.
Question 1
In a binary tree with a series of insertions leading to an imbalance, describe how you would perform successive right and left rotations.
💡 Hint: Map out the tree after several insertions to visualize needed rotations.
Question 2
Explain the consequences of failing to maintain height information in nodes after rotations.
💡 Hint: Consider how balancing impacts retrieval performance.
